c++ - error message: Fatal error: out of memory on a 768 MB machine?

hello,

I run DMC on a win98se machine which has 768 MB installed.
Because I thought 768 MB is more than enough for win98se I deactivated virtual 
memory (Paging=off in [386Enh] of system.ini). After that step dmc complains 
with "Fatal error: out of memory".

I assume it expects Win32 API GlobalMemoryStatus() to return a value != 0 in 
field dwAvailPageFile? Why? Possibly this restriction is not necessary.

The compiler relies on the system having virtual memory for its
implementation of precompiled headers. It's internal memory management is
wrapped up in this even if precompiled headers are not being used.

Thanks for the info! Although I still cannot imagine why the size or existance 
of a swap file should be an issue for an application. Even a 
CreateFileMapping() function call with a hFile argument of -1 (in which case 
the docs say the object is "backed by the operating-system paging file") works 
fine if "virtual memory" is disabled in win9x.
